Definitions
- the invention belongs to the field of analysis of the nucleotide and / or amino acid sequences composing living organisms, in particular the analysis of particular mutations that said sequences may present.
- It relates to methods of identifying and selecting fragments of nucleic acid or protein sequences constituted by and / or comprising motifs exhibiting specific mutability characteristics, it also relates to pharmaceutical compositions containing said fragments for the preparation of medicaments. useful for the treatment and / or prevention of human, animal and / or plant pathologies or for the preparation of therapeutic targets useful for the screening of therapeutic compounds.
- mutations induced in the wild sequences of pathogenic organisms are, for example, responsible for the therapeutic escape mechanisms, that is to say the capacity of pathogenic organisms, viral or bacterial, to resist therapeutic treatment.
- the nucleotide and / or polypeptide sequences of the mutant strains of said organisms indeed have particular mutations compared to the nucleotide or polypeptide sequences of wild strains.
- Such mutations are also determinant of functional changes in genes or proteins which result in the alteration of many biological processes, such as the triggering of the immune response, the infectivity of viruses, the appearance of cancers, etc.
- HIV human immunodeficiency virus
- RT Reverse Transcriptase
- Hepatitis A, B, C, D and E are real public health priorities, due to their Boolean condition and their potential severity.
- the Los-Alamos Library (http://hiv-web.lanl.gov/) provides a large amount of data concerning alignments of HIV protein sequences and related mutations.
- several publications by Ribeiro et al. disclose methods implementing Boolean state calculations of the appearance of resistant mutants using fairly complex mathematical calculations.
- this possibility of mutation corresponds to a Boolean state of said mutation.
- the object of the method of the invention is to identify several patterns whose Boolean state of relative mutation, with respect to a set of given sequences, is predetermined. This method is based on the identification of either motifs or combinations of motifs which have never mutated simultaneously, or of motifs or combination of motifs which mutated simultaneously, at least once on at least one of the sequences of the set and having not mutated on the other sequences of said set.
- the present invention constitutes a new tool for making it possible to find more durable solutions during therapeutic treatments of pathologies involving pathogenic organisms or human genes, exhibiting a high degree of mutability.
- the subject of the invention is also the use of the sequences made up or comprising said motifs and / or combinations of the motifs thus identified for the preparation of medicaments and / or vaccines useful for the treatment or prevention of human, animal or plant pathologies , the preparation of therapeutic targets useful for the screening of such drugs, the docking of a drug on its target, the design of new diagnostic assistance methods, where for example, the choice of one or more Therapeutic compounds would be performed based on the mutability of the pathogens causing the disease in a given patient.
- the term “motif” means a nucleotide capable of forming part of a nucleic acid sequence or of a synthetic oligonucleotide, designated below by its single character code: A, G, C, T or U, corresponding to the nomenclature of the respective base (adenine A, guanine G, cytosine C, or thymine T in DNA, or uracil U in RNA) of which they are made up.
- motif also means an amino acid, whatever its configuration, capable of being part of a natural or synthetic protein or peptide, designated by its unicharacter code such as for example, those represented in the table above .
- Amino acid code
- sequence is understood to mean any chain of motifs as defined above, capable of constituting a sequence of a nucleic acid or a fragment thereof of a living organism or a sequence of a protein or a fragment thereof. -this of a living organism including wild sequences, mutant sequences or alternatively, artificial sequences analogous to these obtained by chemical or biological synthesis according to methods known to those skilled in the art.
- sequence containing such motifs is intended to mean a group of genes, a gene, or a fragment thereof, a group of proteins, a protein or a fragment thereof. this.
- variant of a sequence is meant any sequence differing from the original or wild-type sequence by at least one motif.
- the object of the invention is therefore to identify patterns which have never mutated simultaneously among all the members of a set of sequences.

- the subject of the invention is also the use of the method of identifying motifs described above for the selection of fragments of sequences constituted by and / or comprising motifs which have never mutated simultaneously for the preparation of vaccines.
- Vaccines are made up of antigens made up of molecules or parts of molecules in a pathogenic organism which, when injected into the body, produce a greater number antibodies against said pathogenic organism. These antibodies recognize the molecules against which they are directed and thus allow the immune system to destroy said pathogenic organism.
- the peptides that are part of the envelope proteins of the virus, identified because they cannot mutate together, probably due to genetic pressure or risk losing their functionality, are vaccine candidates of choice.
- the method of identifying peptide motifs makes it possible to select sequences containing said motifs, contiguously or not, in order to develop a vaccine candidate.
- Said vaccine has the advantage, compared to the other vaccines produced by conventional routes, of being described in an exhaustive manner and of containing in a certain manner the regions necessary for the stability of said vaccine precisely by the choice of the sequences which cannot mutate together simultaneously , thus destroying the pathogenic organism.
- the invention also relates to the use of the fragments of sequences constituted by and / or comprising nucleotide and / or peptide motifs of the sequences analyzed, having never mutated simultaneously for the preparation of vaccines.
- the invention also relates to the use of such a method of identifying patterns or of combining patterns which have never mutated simultaneously for the design of diagnostic aid tools.
- Another subject of the invention is the use of such an identification method for the selection of sequence fragments constituted by and / or comprising motifs which have always mutated simultaneously for the preparation of diagnostic tests.
- the method of the invention also makes it possible to build a knowledge base which constitutes a decision-making aid tool, for example during the determination by the doctor of the administration of anti-viral treatments to a given patient. .
- the method for identifying patterns which have never mutated simultaneously comprises an additional step consisting in comparing data relating known drug resistance to the mutations observed, for example in the cases of HIV to the data disclosed by J. Hammond et al. in "Mutations in Retroviral Genes Associated with Drug Resistance”. (The Human Retroviruses and AIDS Compendium. 1999)
- the mutated drug-amino acid relationship is very useful for optimizing treatment.
- the comparison of the peptide motifs is carried out on three subsets of a protein database, that of reverse transcriptase, that of protease and that of integrase (http : //hiv-web.lanl.gov/).
- the method of the invention then makes it possible to identify the mutations induced under the selection pressure.
- the method of the invention comprising the comparison with said drug resistance allows to choose a combination of drugs so that the amino acid mutations likely to be caused by each of the antivirals, likely to confer resistance to different drugs involved in this combination (less than a dozen), do not occur simultaneously.
- the practitioner can then use the information obtained by applying this method, for example to isolated viral sequences, or deduced from the isolated viral genome, of a given patient to ensure that the envisaged HAART is indeed the most effective possible.
- the method of identifying peptide regions which have not mutated simultaneously according to the invention also provides valuable assistance when resistance develops in patients who have already been treated.
- the method according to the invention can for example be applied to subsets of polypeptide sequences among which is included that or those deduced from the sequencing of the viral genome isolated from the patient.
- the method of identifying peptide motifs which have not mutated makes it possible to use a combination therapy designed so as to maintain the selection pressure on the mutation.
- the molecule thus selected will be accompanied by two or three other antiretrovirals which target areas of the protein which cannot mutate at the same time as the area which has already mutated.
- the identification of patterns, within the same gene, having mutated at least once simultaneously on at least one variant and never having mutated on the other variants makes it possible to identify regions of said gene capable of exhibiting a physical or functional interaction.
- the identification of the motifs which have never mutated simultaneously makes it possible to identify regions of said gene whose mutual presence is essential and essential to its function.
- the subject of the invention is also the identification, on a set of genes or on a set of non-coding sequences, of patterns which have never mutated simultaneously. The identification of such motifs makes it possible to select gene regions capable of exhibiting physical or functional interactions throughout the genome.
- Another subject of the invention relates to the use of such a method of identifying motifs or combinations of motifs for the selection of fragments of sequences constituted and / or comprising motifs which have never mutated simultaneously for the preparation of therapeutic targets.
- Yet another subject of the invention relates to the use of fragments of sequences constituted by and / or comprising motifs either having mutated simultaneously at least once on at least one sequence of the set and having never mutated on the other sequences of the set for the preparation of therapeutic targets.
- a subject of the invention is also the use of the motifs or combinations of motifs thus identified to prepare therapeutic targets useful for the screening of new therapeutic compounds intended for the prevention and / or treatment of human, animal or plant pathologies.
- the preparation allows the preparation of a therapeutic target against which will be tested therapeutic compounds directed against said pathogenic organism and in particular therapeutic compounds against which the wild pathogenic organism will not be able to develop resistance mutations.
- fragments made up and / or comprising of motifs which have never mutated simultaneously is also useful for the preparation of diagnostic tools where it is not always easy to quickly detect such or such type or subtype of organism pathogenic, because the identification of peptide motifs according to the invention allows the preparation of peptide fragments comprising the most representative motifs of a subtype of pathogenic organism. These fragments are then used in detection tests, like immunoenzymatic tests, for example.
- This application of the method of the invention consists in identifying a set of motifs essential for the function of a protein from a human, animal or plant organism or from a pathogenic organism. These motifs can constitute, for example, a subset of amino acids known to play an important role in the function of the targeted protein.
- the motifs thus identified are contiguous motifs of the gene sequence and represent a linear sequence of said gene.
- the patterns identified are patterns which are not contiguous on the linear sequence of the gene. They can then be useful for completing studies three-dimensional analysis in order to confirm a possible non-linear spatial proximity of said patterns.
- the method of the invention may then include a new additional step (g), after step (e) of identifying the patterns, consisting in comparing said patterns with the data of three-dimensional structures of these proteins such as the amino acids involved. in the catalytic site and / or in the sites linked by non-competitive inhibitors.
- the subject of the invention is also the use of fragments of sequences constituted by and / or comprising peptide motifs which have always mutated simultaneously for the design of diagnostic aid tools.
- the method of identifying peptide regions according to the invention defines the most representative peptides of a subtype. Once identified, these peptides are used in any detection test known to those skilled in the art, such as immunoenzymatic tests, of the ELISA type, for example.
- the search for peptides representing a subtype of a particular type is carried out as indicated above. It is a question of finding peptide antigens capable of being recognized by a particular serum containing or not the antibodies of a particular subtype.
- the method according to the invention can be applied to any bank of sequences, the results are compared by subtypes and the theoretical peptide combination most representative of a particular pathogenic type is thus identified.
- the peptides thus identified are synthesized and immunologically tested against a collection of sera.
- the invention is of great interest when it is used to identify either motifs which have mutated at least once together, or which has never mutated from a large number of sequences comprising a large number of motifs in order to select sequences of patterns useful for the various applications envisaged above.
- the example below shows the different matrices formed during a comparison of patterns performed on a subset of eight sequences, using the SVRLGHKDE V reference sequence.
- A1 0, if motif mutated with respect to the reference sequence
- A2 l, if other case (motif not mutated with respect to the reference sequence).
- Cl l, if a couple of patterns mutated simultaneously, or never mutated.
